Bank Balance-Sheet CRE Lending by Bank Size

Introduction

Banks are the largest source of commercial real estate debt and the most cyclical, and the key to understanding them is that "banks" is not one lender but two. At a money-center bank like JPMorgan or Wells Fargo, commercial real estate is a relatively small, originate-to-distribute sideline; at a regional or community bank, it is often the core business, and the concentration can run high enough to threaten the institution itself. That divide explains nearly everything about how bank CRE lending behaves. Commercial real estate makes up roughly 13% of large US banks' balance sheets but around 44% of regional ones, and banks in aggregate hold about $1.9 trillion of income-property mortgage debt, the single largest share of the market. When that lending expands or contracts, it moves the entire market, which is exactly what happened when regional banks pulled back hard in 2023 and 2024.

A bank lends on real estate differently from any other CRE lender because of how it funds itself and what it optimizes for. It raises money largely through deposits, which are cheap but can leave quickly, and it earns the net interest margin between deposit costs and loan yields. That funding model makes banks the natural home for two kinds of CRE lending other lenders avoid: construction loans, which require active monitoring and draw management, and relationship loans, where a thin lending spread is acceptable because the borrower also brings deposits, treasury management, and other fee business.

Relationship lending

Lending priced and extended on the strength of a broader client relationship rather than the loan's standalone economics. A bank may accept a slim spread on a CRE loan because the borrower keeps deposits, uses the bank's treasury services, and brings other fee-generating business, making the overall relationship profitable even when the loan alone is not.

The dependence on deposits is also what makes banks the most cyclical CRE lenders. When deposits are plentiful and capital ratios are comfortable, banks lend aggressively; when deposits flee or regulators flag risk, they retrench fast. No life insurer or agency behaves this way, which is why bank lending is the swing factor that tightens or loosens the whole market and the most cycle-sensitive force in the CRE debt universe. The contrast with the steady, liability-matched life insurance lender is stark: where the insurer lends through the cycle by design, the bank amplifies it.

The single most important distinction in bank CRE lending is size, because the two tiers run fundamentally different models.

Money-center banks: originate to distribute

The largest banks treat CRE as a modest line of business, holding it at roughly 6.8% of assets at the very largest institutions. They often originate large loans intending to securitize or syndicate them rather than hold them, which makes them partly a feeder into the CMBS market rather than pure portfolio lenders. For every $100 of asset growth, large banks direct only about $3.32 into CRE loans. CRE is something they do, not something they are.

Regional and community banks: the core business

Regional and community banks are the opposite. CRE can be close to half their balance sheet, and for every $100 of asset growth they steered about $37.30 into CRE, more than eleven times the large-bank rate. They hold what they originate, carry a higher share of construction loans, and lean local, lending against properties and sponsors they know in their own markets. This concentration is the source of both their importance and their fragility: regional and community banks are roughly three times more exposed to CRE than the big banks, so a CRE downturn lands on them first and hardest.

Because CRE concentration has toppled banks before, regulators watch it closely through specific supervisory thresholds. A bank whose total CRE loans exceed 300% of total capital, or whose construction loans alone exceed 100% of capital, is flagged for heightened supervisory analysis of its concentration risk.

Exceeding the threshold is not an automatic problem, but it draws supervisory scrutiny, pressures the bank to slow or shrink its CRE book, and raises the regulatory capital it must hold. The result is procyclical: concentration limits bite hardest exactly when CRE values are falling and loans are migrating to watchlists, pushing banks to pull back at the worst possible moment for borrowers needing to refinance. The pressure is most acute where values fell furthest, which is why bank office exposure has driven so much of the current strain, a dynamic traced in office distress, workouts, and restructurings.

The 2023 regional banking crisis exposed how tightly bank CRE lending is bound to deposits. When Silicon Valley Bank and First Republic failed, depositors across the regional banking system grew nervous, funding costs jumped, and banks already heavy in CRE faced a squeeze from both sides: their cost of funds rose while examiners pressed them to reduce CRE exposure.

Layered on top is a maturity wall: a large volume of CRE debt comes due in the next few years, and much of it sits with banks that may be unwilling or unable to refinance it on the original terms. That gap between maturing bank loans and reduced bank appetite is the opening that debt funds and private credit RE lending have rushed to fill.

The practical takeaway is to read bank appetite by tier and by cycle. A construction loan or a relationship-driven deal on a local asset points to a regional or community bank; a large loan that will be syndicated or securitized points to a money-center institution that lends to distribute. The construction and bridge financing that banks specialize in, and the conditions under which they extend it, are detailed in bridge and construction lending.

What makes banks the market's swing factor is the gap between the two tiers. CRE is a small originate-to-distribute sideline for the money-center banks but the core business for regionals, where it can reach 44% of assets against roughly 13% at the giants. Because regionals fund those loans with deposits, a deposit scare like 2023, layered on concentration limits around 300% of capital, forces them to retrench just as borrowers most need to refinance, which is why banks amplify the cycle while life insurers and agencies steady it. Their retreat after 2023 is precisely what handed origination share to the debt funds, and their eventual return is the signal the whole market watches for a turn.
